因此，我成功地使用 /clr 标志将我正在开发的项目编译为 .lib。我现在正在努力为它创建一个 CLR 类库包装器，以允许我将它与 .NET 一起使用。

尝试编译 CLR 类库时出现以下错误：

Renderer.obj : error LNK2028: unresolved token (0A000017) "public: __thiscall cMain::cMain(void)" (??0cMain@@$$FQAE@XZ) referenced in function "private: void __clrcall Renderer::GraphicsBox::NewGraphicsBox(int,int,int,int)" (?NewGraphicsBox@GraphicsBox@Renderer@@$$FA$AAMXHHHH@Z)

Renderer.obj : error LNK2019: unresolved external symbol "public: __thiscall cMain::cMain(void)" (??0cMain@@$$FQAE@XZ) referenced in function "private: void __clrcall Renderer::GraphicsBox::NewGraphicsBox(int,int,int,int)" (?NewGraphicsBox@GraphicsBox@Renderer@@$$FA$AAMXHHHH@Z)

我已将相关条目添加到包含目录，以及相关条目到 lib 目录。

代码如下所示：

标准数据文件

#pragma once

#include "cMain.h"

渲染器.h

#pragma once

#include "Stdafx.h"



using namespace System;

namespace Renderer {

    public ref class GraphicsBox
    {
        GraphicsBox();
        ~GraphicsBox();

        void NewGraphicsBox(System::Int32 scrw, System::Int32 scrh, System::Int32 posx, System::Int32 posy);
        // TODO: Add your methods for this class here.
    };
}

渲染器.cpp

#include "stdafx.h"

#include "Renderer.h"

pragma comment(lib "DX11test.lib")

using namespace Renderer;

GraphicsBox::GraphicsBox()
{

}

GraphicsBox::~GraphicsBox()
{

}

void GraphicsBox::NewGraphicsBox(System::Int32 scrw, System::Int32 scrh, System::Int32 posx, System::Int32 posy)
{
    cMain *base;

    bool result;

    base = new cMain;
    if (!base)
    {
        throw runtime_error("Failed at base = cMain");
    }
}

我要参考的课程：

cMain.h

#ifndef _CMAIN_H_
#define _CMAIN_H_

#define WIN32_LEAN_AND_MEAN
#include <Windows.h>
#include <vector>
#include <map>
#include <string>

#include "InputHandler.h"
#include "cGraphics.h"
#include "cVehicleObject.h"
#include "cVehicleModel.h"
#include "cTerrainModel.h"
#include "cLight.h"

using namespace std;

public class cMain
{
public:
    cMain();
    cMain(const cMain& other);
    ~cMain();

    bool Initialize(int scrWidth, int scrHeight);
    void Shutdown();
    void Run();

    LRESULT CALLBACK MessageHandler(HWND hwnd, UINT umessage, WPARAM wparam, LPARAM lparam);
private:
    bool Frame();
    void InitializeWindows(int& scrw, int& scrh);
    void CreateNewWindow(int& scrw, int& scrh, int posx, int posy);
    void ShutdownWindows();

    void ErrorDump(vector<string> errors, string filename);
    void ErrorDump(string error, string filename);

    bool SetUpLights();
    bool SetUpObjects();

    LPCWSTR m_applicationName;
    HINSTANCE m_hinstance;
    HWND m_hwnd;

    InputHandler* m_input;
    cGraphics* m_graphics;

    cObject::GameObjects m_gameObjects;

    vector<cLight> m_lights;
};

static LRESULT CALLBACK WndProc(HWND hwnd, UINT umessage, WPARAM wparam, LPARAM lparam);
static cMain* ApplicationHandle = 0;

#endif

我的直觉告诉我，这与在我试图设置为 lib 的项目中使用 Windows API 有关，但我缺乏将事物链接在一起的经验，所以老实说我不知道​​。

我想将整个事情转换为完全对 CLR 友好，我不想不遗余力。谢谢您的帮助

链接器错误与程序的包含路径无关，它与函数的实现有关。在您发布的示例中，我没有看到cMain.cpp，所以您可能忘记实施它或者您只是忘记实施cMain::cMain()
